No they use a numbing spray then punch a small hole then pull the vas deferens out the small hole and do the procedure. It heals up to a pin hole sized mark that can barely be seen.
I was in to work that night on desk duty(with ice packs) for a few weeks rather than my normal heavy lifting which I went back to soon after.
For that to work some people have to get too much pressure. Your clean ass will have been built on the live lost to excessive bidet pressure.
